Clearly Erroneous Execution

On September 10, 2010, the SEC approved rules that expanded the stock-by-stock circuit breakers and clarified the process for breaking erroneous trades.  These changes were incorporated into the NYSE Arca Equities Rule 7.10.  These changes were also adopted by the other exchanges in the national market system. For details, please see the Clearly Erroneous Execution (CEE) Rule and Procedure Changes (pdf).

A transaction is defined as “clearly erroneous” when there is an obvious error in any term, such as price,  number of shares or other unit of trading, or  identification of the security. CEE Requests for Review are processed using a web-based submission service, which was designed to expedite and simplify the review  process.

All NYSE, NYSE MKT, or NYSE Arca Submission Forms, and detailed CEE guidelines and policies are available on the NYSE Euronext Clearly Erroneous Execution Customer Submission website. For easy retrieval and access to the submission website, please bookmark https://www.nysenet.com/cee/welcome.do.

In the event that the website is not accessible, customers may submit a request via a Word document available at CEE NYSE Arca Submission Form (.doc).  To process the request in this manner, please save the form to your computer desktop with the  relevant information and e-mail the attachment to NYSE Arca at ceenysearca@nyx.com.
